Hello there
I ran into two bugs in version 1.62 and 1.61:
first bug: I can't visit the gym anymore. The first sessions with both Rachel and the male trainer (forgot the name) were triggered, but after these two sessions, I could not access the gym anymore. I tried it on every weekday at every possible time. It always says "there is no need for me to go there".
second bug (maybe it has something to do with the first bug): the game does kind of not recognize, that I bought the gym outfit. I can buy the gym outfit and it shows up in the wardrobe. If I now exit the game, start the game again and load the latest save file, I can buy the gym outfit again. Even though the gym outfit is still in the wardrobe and the game reacts when I try to wear the gym outfit and leave the room.
I jumped from version 1.58 to 1.61 and did not play the versions between these two.
